I'm trying to upload a file from front end to save in the database. But Spring controller is failing to receive the file.

HTML

JS

var myApp = angular.module('myApp', []);

myApp.directive('fileModel', ['$parse', function ($parse) {
            return {
               restrict: 'A',
               link: function(scope, element, attrs) {
                  var model = $parse(attrs.fileModel);
                  var modelSetter = model.assign;

element.bind('change', function(){
                     scope.$apply(function(){
                        modelSetter(scope, element[0].files[0]);
                     });
                  });
               }
            };
         }]);

myApp.service('fileUpload', ['$http', function ($http) {
            this.uploadFileToUrl = function(file, uploadUrl){
               var fd = new FormData();
               fd.append('file', file);

$http.post(uploadUrl, fd, {
                  transformRequest: angular.identity,
                  headers: {'Content-Type': undefined}
               })

.success(function(){
               })

.error(function(){
               });
            }
         }]);

myApp.controller('myCtrl', ['$scope', 'fileUpload', function($scope, fileUpload){
            $scope.uploadFile = function(){
               var file = $scope.myFile;

console.log('file is ' );
               console.dir(file);

var uploadUrl = 'fileUpload';
               fileUpload.uploadFileToUrl(file, uploadUrl);
            };
         }]);

Spring Controller

Content of the file in Spring controller is null. Any idea on this?
